Based on the given information, if there is a many-to-one mapping between the set of Zip Code(s) and City in a table, then the database is not in the third normal form (3NF). The presence of transitive dependencies, as indicated by the many-to-one mapping, violates the rules of 3NF.
Therefore, the integer x representing the normalization level is 3.
